Check your .conf file, there is something not good

Did you tried to rebuild it ? (assuming you are using NGINX as reverse proxy for apache)

cd /usr/local/directadmin/custombuild
./build update
./build set webserver nginx_apache
./build nginx_apache
./build rewrite_confs

root@Server01-> ./build set webserver nginx_apache
webserver is already set to nginx_apache
root@Server01-> ./build nginx_apache
.....
checking whether we are cross compiling... configure: error: in `/usr/local/directadmin/custombuild/httpd-2.4.51/srclib/apr':

If you meant to cross compile, use `--host'.
See `config.log' for more details
configure failed for srclib/apr

i try this:
root@Server01-> yum reinstall gcc gcc-c++ make
